boundary conditions / material parameters from STEP files

hi!

is it possible to read in boundary conditions or material parameters of parts of models contained in STEP files (for FEM). i think the STEP standard supports these kind of things. is OCC capable of supplying that data?

thx

Hello Robert,
my guess is that OCC would read those informations if they are in the step file. You might want to try this simple test just to see if a step entity exist (I know they have package StepFEA and StepElement that have FEM stuff):

STEPControl_Controller::Init();
STEPControl_Reader aReader;
IFSelect_ReturnStatus stat=aReader.ReadFile("femFile.stp");
Handle_StepData_StepModel aStepModel=aReader.StepModel();
for (Standard_Integer i=1; i<=aStepModel->NbEntities(); i++) {
std::cout << i<<"- NAME:"<Entity(i)->DynamicType()->Name()<
